Hi Julien - OK, if we're going to do one of your big queries, can we please start fresh, make a new discussion at https://github.com/sqlalchemy/sqlalchemy/discussions , give me **really really succinct** models + the query you want, etc. the google groups thing here is not exactly going away but it's an antiquated interface at this point.

Thank you Mike, it _almost_ work. With (1) SQLAlchemy now generates (2). I'm still getting an error: sqlalchemy.exc.ProgrammingError: (psycopg2.errors.UndefinedTable) invalid reference to FROM-clause entry for table "content" LINE 4: WHERE content_1.id = content.id UNION ALL SELECT content.id ... ^ HINT: Perhaps you meant to reference the table alias "content_1". This is because the WITH statement appears at the "top" rather than a subselect (and cannot reference the outer table) Any idea how could I transform (1) to generate (3) rather than (2) ?

[sqlalchemy] orm.column_property()
Hello, I'm trying to add a column_property to recursively load and merge some json column. I have the following: https://gist.github.com/silenius/1af1072abae5829f54584f1ea554e074 but I cannot figure how can I replace the '5011' at line 11 (which is the object primary key) with the "current" involved objet..? For example when I'm doing dbsession.get(MyClass, 1234) I cannot figure how reference the id in the column_property query Any idea ?
